amplitudfel
Amplitudfel is a theoretical metric used in signal processing to quantify the deviation between the instantaneous amplitude of a waveform and a predefined reference envelope. It provides a concise way to describe how much a signal’s amplitude strays from its intended level over time, which can be important in systems that require tight amplitude control.
Amplitudfel at time t can be described as the difference between the actual instantaneous amplitude A_actual(t)
Amplitudfel is a time-varying, signed quantity that can be positive or negative depending on whether the actual
The concept is applicable in power and audio amplifiers, automatic gain control loops, envelope tracking in
The term combines amplitude with fel, a word element for error in several Germanic languages. Related concepts
